Is the 2007 GMC Sierra Duramax a good truck? I have read that the lbz is one of the best duramax motors to have. The truck I am looking at has 93000 miles on it which I feel is not bad for a 07 truck. Its a one owner truck and the reason he is selling it is to buy a dump truck to use on his farm. Any thoughts on this model year truck? Thanks

The lbz is a good engine. The biggest benifit is it doesn't have a ton of emissions stuff, and it doesn't have the the injector issues the earlier ones have. It was only availible on the gmt800 trucks(2007 would be sierra classic) so it would be better in 99-06 section.
